BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting remote control system for controlling lighting of lighting equipment by remote control.

0002

2. Description of the Related Art Conventionally, remote control systems for lighting have been provided for controlling lighting of lighting equipment by remote control. In this type of remote control system for lighting, the lighting state of the lighting equipment is controlled by a transmitter that emits infrared rays, etc., and in order to improve the appearance of the lighting equipment, a lighting switch is used to control the lighting using a drawstring. There is something that has been lost.

0003

However, when the lighting equipment itself is not equipped with a lighting switch, there is a problem in that the lighting state of the lighting equipment cannot be controlled if the transmitter is lost. Incidentally, recently, it has become popular to remotely control the operation of home appliances such as televisions, audio systems, and air conditioners. Therefore, if the transmitter of the remote control system for the lighting fixture is lost, it may be possible to control the lighting using the transmitter of the remote control system for the other home appliances.

[0004] However, in July 1987, the Home Appliance Association of Japan announced that with this type of remote control system for home appliances, it was not possible to control devices between different types of remote control systems or between different manufacturers. It is recommended to use remote control signals to prevent malfunctions. Therefore,
In conventional remote control systems for lighting, it has not been possible to control the lighting of lighting equipment using a transmitter of another remote control system.

[0005] The present invention has been made in view of the above points, and its object is to use the transmitter of another remote control system to temporarily restore lighting equipment even when the transmitter is lost. An object of the present invention is to provide a remote control system for lighting that can control lighting.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention identifies codes commonly used in remote control signals defined in remote control systems for home appliances, and provides a system having the common code. The lighting device includes a control means that switches the lighting state of the lighting device every time a remote control signal is input.

[0007] When the control means is temporarily operated, it is preferable to operate it when a switch provided on the lighting equipment is operated.

[0008]

[Operation] By configuring the present invention as described above,
Regardless of whether the control means is for a lighting device or not, when it receives a remote control signal from the transmitter, it can control the lighting of the lighting device, so that it can be used even if the transmitter is lost. It is possible to control the lighting of lighting equipment using the transmitter of the remote control system.

[0009]

Embodiment FIGS. 1 to 3 show an embodiment of the present invention. First, I will explain the remote control system for home appliances recommended by the Home Appliances Association. In this remote control system, it is recommended to use the following remote control signals in order to prevent devices from being controlled and malfunctioning between different types of remote control systems and between different manufacturers. This remote control signal has a carrier wave of 900 to 95
Uses 0nm infrared rays, subcarrier is 33KHz or more 40
KHz or less, the transmission signal is modulated using the PPM method, this modulation signal performs primary modulation that amplitude modulates the subcarrier, and this primary modulated signal performs secondary modulation that amplitude modulates the infrared rays. It is something that is formed.

FIG. 3 shows the format of the above transmission signal. This transmission signal includes a reader L as a marker indicating the beginning of the signal, custom codes C0 and C1 which are codes for identifying the supplier of the product, data D0 to Dn indicating control details, and indicating the end of the signal. It consists of a trailer TR as a marker. Here, the basic pulse width T is
0.35ms<T<0.5ms, the leader L is defined to have a high level period of 8T and a low level period of 4T, as shown in FIG. 3, and the trailer TR has a high level period of T. It is stipulated that the low level period be 8 ms or more. Further, the custom code is defined as four digits in hexadecimal, and this custom code is registered and used by each company.

[0011] In the above transmission signal, the leader L and trailer TR are common between different types of remote control systems and between different manufacturers. Therefore, in this embodiment, even if the transmitter is lost, lighting control of the lighting equipment can be performed using a remote control signal from a transmitter of another remote control system having the reader L and trailer TR. It is.

FIG. 1 shows a circuit of a lighting fixture whose lighting is controlled by the lighting remote control system of this embodiment. In this lighting fixture, a load consisting of a lamp L and a miniature bulb M is connected to an AC power supply AC via a room wall switch SW1, and a reception control circuit 1 is controlled by a remote control signal from a transmitter (not shown). The reception control circuit 1 is powered by a voltage created by lowering the voltage of an alternating current power supply AC, rectifying and smoothing it, and stabilizing the output in a voltage regulator circuit 15. The remote control signal is received by the receiving section 2 of the receiving control circuit 1, and the output of the load state selection circuit 3 which receives the output of this receiving section 2 causes two relays R to be connected.
Controls the operation of y1, Ry2, lamp L and miniature bulb M
The lighting of the lamp L and the miniature bulb La is controlled by opening and closing contacts r1 and r2 of relays Ry1 and Ry2 inserted in series, respectively.

The load state selection circuit 3 includes a control section 4 made of an IC, and the control section 4 controls the operation of the load by reading data in a remote control signal specified by the Home Appliance Association. I do. As shown in FIG. 2, this control section 4 inputs the signal from the reception section 2 to the code determination section 6 via the input section 5, and determines that the received signal is a regular remote control signal. In addition, by identifying the custom code, it is determined whether it corresponds to the custom code, and further, the content of the load operation control is determined from the data. Mode setting section 9
is used to set the number of loads, the number of data types of remote control signals, etc., and the code determination section 6 performs the above determination according to the settings of the mode setting section 9. The output state forming section 7 forms an appropriate output signal according to the output of the code determining section 6, and outputs it via the output section 8.

Now, when a remote control signal for lighting the lamp L is received from the regular transmitter of the lighting remote control system of this embodiment, the output P1 of the control section 4 is activated in response to this remote control signal.
is at low level, and output P2 is at high level. At this time, relay Ry1 is driven and relay Ry2
becomes a non-driving state, and the contact r1 closes, causing the lamp L to light up. Similarly, when lighting the miniature bulb M, when a remote control signal containing data for lighting the miniature bulb M is sent from the transmitter, the output P1 of the control section 4 becomes high level and the output P2 becomes low level. As a result, contact r2 of relay Ry2 closes and miniature bulb M lights up. When turning off the lamp L and the miniature bulb M, the output P
1 and P2 both become high level, contacts r1 and r2 of relays Ry1 and Ry2 both open, and both lamp L and miniature bulb M go out.

In addition, in consideration of the provision of the lighting switch SW2 which is switched by a pull string, the control unit 4 includes an input determining unit 10 that determines the switching state of the switch SW2, and an input determining unit 10 that determines the switching state of the switch SW2 and avoids chattering that occurs when switching. A chattering avoidance section 11 is provided, and the same input signal as that of the code determination section 6 is given to the output state forming section 7 according to the switching state of the switch SW2, so that lighting control of the lamp L and the miniature bulb M can be performed. The clock generating section 12 in the control section 4 generates a clock signal for the operation of the entire control section 4, and the reset section 13 generates a clock signal that is input when the battery B for the control section 4 is connected. The input section 5, code determination section 6, and output state forming section 7 are set to the initial setting state by a reset input.

[0016] The above is the configuration provided in the lighting equipment of the conventional remote control system, but in the case of this embodiment, when the transmitter is lost, the operation of the load is controlled by the transmitter of another remote control system. The code determining section 14 receives an output from the input section 5 when the switch SW3 is operated. This code determination unit 14 determines whether the input remote control signal is a remote control signal recommended by the above-mentioned Home Appliances Association. If the signal is the same, an output to turn on or turn off the lamp L is given to the output state forming section 7. For example, when a remote control signal is received from a transmitter of another remote control system, the lamp L is turned on, and when a remote control signal is received again, the lamp L is turned off. In this way, if you lose the transmitter of the lighting remote control system, by operating switch SW3,
The lighting of lighting equipment can be temporarily controlled using the transmitter of other remote control systems.

By the way, if the lighting of a lighting fixture is controlled using the transmitter of another remote control system in this way, the equipment of the other remote control system may operate, or conversely, the equipment of the other remote control system may be operated. There is a concern that the lighting of the lighting equipment will be controlled when the operation is performed, but there is no such concern if the remote control system for lighting uses the transmitter of another remote control system. In other words, lighting fixtures are generally attached to the ceiling surface, and transmitters for general home appliances have a smaller output than transmitters for lighting fixtures. Therefore, when controlling the lighting of a lighting fixture using a transmitter for this type of home appliance, the transmitter should be directed toward the lighting fixture (directed with a determined aim), and should be brought close to the lighting fixture. Otherwise, it will not be possible to control the lighting of the lighting equipment. In other words, this means that the lighting of the lighting equipment is not controlled by normal operations for controlling home appliances. The reason why the output of the transmitter of the lighting remote control system is larger than the output of the transmitter of other remote control systems is as follows. In lighting equipment, especially inverter-type lighting equipment, the light emitted from the fluorescent lamp contains infrared rays with a transmission frequency close to the frequency of the subcarrier output from the transmitter, so infrared rays from the fluorescent lamp cannot cause malfunctions. Since the S/N ratio for the infrared rays is set high so that the infrared rays do not occur, the output from the transmitter is larger than the output from a transmitter of a normal home appliance. Therefore, both lighting equipment and home appliances can be controlled by the same transmitter without any problem. Therefore, it is possible to improve the appearance by eliminating the switch SW2 which is operated by a drawstring.

[0018]

[Effects of the Invention] As described above, the present invention identifies codes commonly used in remote control signals defined in remote control systems for home appliances, and
Each time a remote control signal having the above-mentioned common code is input, the controller is equipped with a control means that switches the lighting state of the lighting equipment, so the control means can control whether it is for a lighting equipment or not. When receiving a remote control signal, you can control the lighting of the lighting equipment.
Even if the transmitter is lost, the lighting of the lighting equipment can be temporarily controlled using the transmitter of another remote control system. Therefore, it is possible to improve the appearance by eliminating the switch SW2 which is operated by a pull string.
